Terrible customer service. My unit was flashing and was told to change the battery. It’s wired in, I’m disabled not an electrician. They sent me a new unit, that also had a flat battery and was talked through how to reset it, which cut off my phone line snd unit didn’t work due to the flat battery . Finally got a female customer service operator who sent me another unit, plugged in and worked straight away. This was a careline box, not a lifeline box. I feel they were trying to get rid of old untested stock? Very poor service. Apart from that I was charged £50 more than the advertised price this year. Guess who won’t be renewing nrxt tear? Help line operators can’t be faulted, but customer service need some training, except for excellent female operators. Males seem to have no interest which can be heard in their voices, that is when you can even hear them, both male operators said it was a bad line but the female lines were 100% . Most odd. I will look elsewhere for my help next year, I would now except I read the refund process is “difficult” which I read as non existant
